DESCRIPTION
The GTL2000 provides twenty-two bits of high-speed voltage
clamps. The low ON-state resistance of the clamp allows
connections to be made with minimal propagation delay.

The device is organized as one 22-bit voltage clamp. When S or D
is low the clamp is in the ON–state and a low resistance connection
exists between the S and D ports. When S port and D port are high,
the clamp is in the OFF-state and a very high impedance exists
between the S and D ports. When the D port is high, the voltage on
the S port is clamped to the applied reference voltage on the GREF
port.

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150°C.
3. The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
